Sup guys latly i been having problems startin my engine. I had my fuel pump die on me last summer and then i put a new one in. I need to know what the fuel Pressure is suppost to be to startt eh truck. I read on a site it should be like 55-60 to start the truck. I just tested mine and im gettin like 40psi when cranking the engine then slowly climbs to like 55-60 then the engine starts. then at idle its 54. does anyone know what its suppost to be and what my problem would be. possibly fuel pump??
